I only use the GPS for Google navigation or with a geocaching application. Since I know where I'm going most days and I don't cache all the time, my GPS is set for "911 only". I turn it on when I need it.

If you're using some location based app where cell tower triangulation is not sufficient to get the job done, then leave it on all the time.

sorry i probbaly wasnt 100% clear on my first post. the gp indicator I was refering to is the compass looking thing. when i have gps off it still there with no waves on it but when its off the waves go away. i was wondering if there was any way to get rid of the thing all together.
